A conjecture from the second author’s paper [Linear Algebra Appl., 332–334 (2001) 519–531] concerning a family of polynomials is proved and strengthened. A consequence of this is that for any n ≥ 4 there is an n × n matrix that is not similar to a Toeplitz matrix, which was proved before for odd n and n = 6, 8, 10.
